Intel X520-SR2 E10G42BFSR 사용자 설명서

Unified Networking and Storage

The family of Intel Ethernet X520 server adapters lowers your 
data center total cost of ownership (TCO) by providing the ability 
to route LAN and SAN traffic over a single fabric.

Support for Fiber Channel over Ethernet (FCoE)
FCoE encapsulates Fiber Channel frames over standard Ethernet 
networks, enabling Fiber Channel to take advantage of 10 GbE  
networks while preserving its native protocol. The X520 server  
adapters offer FCoE hardware acceleration to provide performance  
comparable to FC HBAs. The new server adapters support Data 
Center Bridging, also known as Converged Enhanced Ethernet 
(CEE), which allows customers to configure traffic classes and 
priorities to deliver a lossless Ethernet fabric. An Intel Ethernet 
X520 server adapter reduces TCO by eliminating redundant fabrics  
and saves the cost of expensive FC HBAs and FC switch ports.

Support for iSCSI
The server adapters provide complete support for proven native 
OS and VMM iSCSI initiators as well as iSCSI boot. Historically, 
CRC32C computation has degraded system performance, but 
now with the CRC instruction set included in the latest Intel® 
Xeon® processors, CRC validation is possible with minimal impact 
to network throughput while delivering superior data integrity.

The new Intel Ethernet family of X520 server adapters do it all:  
10 Gigabit LAN, FCoE, and iSCSI; truly delivering on the promise  
of unified networking.

Reliable Performance

The family of X520 server adapters include a number of advanced 
features that allow it to provide industry-leading performance 
and reliability.

Security Optimizations
The adapters support IPsec offload for Microsoft’s Network Access 
Protection (NAP), Active Directory,* and future security capabilities 
in Windows* 7. An X520 server adapter allows customers to run a 
secure network environment without sacrificing performance. 

PCIe v2.0 (5 GT/s)
PCIe v2.0 (5 GT/s) support enables customers to take full advan-
tage of 10 GbE by providing a maximum of 20 Gbps bi-directional 
throughput per port on a single dual port card.

Designed For Multi-core Processors
Support for technologies such as Intel® QuickData, multiple  
MSI-X vectors, and Low Latency Interrupts allow the X520  
server adapters to provide high-performance, 10 Gigabit connec-
tivity in multi-core server blades. These technologies distribute 
network processing across multiple CPU cores, improving  
overall performance.

For today’s demanding virtualized data center environments,  
the new family of X520 server adapters deliver ultimate  
flexibility and scalability.

Intel® PROSet Utility for Windows* Device Manager

Provides point-and-click management of individual adapters, advanced adapter features, connection 
teaming, and virtual local area network (VLAN) configuration 

Time Sync (IEEE 1588, 802.1as)

•  Lets networked Ethernet equipment synchronize internal clocks according to a network master clock; 

endpoint can then acquire an accurate estimate of the master time by compensating for link latency

I/O Features for Multi-core Processor Servers

Intel® QuickData Technology

•  DMA Engine: enhances data acceleration across the platform (network, chipset, processor),  

lowering CPU usage

•  Direct Cache Access (DCA): enables the adapter to pre-fetch the data from memory, avoiding cache 

misses and improving application response time

MSI-X support

•  Minimizes the overhead of interrupts
•  Allows load-balancing of interrupt handling between multiple cores/CPUs

Low Latency Interrupts

•  Based on the sensitivity of the incoming data, the adapter can bypass the automatic moderation  

of time intervals between the interrupts

Header Splits and Replication in Receive

• Helps the driver focus on the relevant part of the packet without the need to parse it

Multiple Queues: 16 queues per port 

• Network packet handling without waiting or buffer overflow providing efficient packet prioritization
